Description
Die vorliegende Erfindung betrifft ein Verbindungselement und ein Verfahren zur Montage eines Verbindungselementes sowie eine Verbindungsvorrichtung für Rohre zur medizinischen Verwendung.The The present invention relates to a connector and a method for mounting a connecting element and a connecting device for pipes for medical use.
Wie es gut bekannt ist, ist es oft im medizinischen Gebiet erforderlich, eine Fluid-Verbindung zwischen Leitungen zur Förderung von Flüssigkeiten zu erzeugen.As it is well known, it is often required in the medical field a fluid connection between lines for the conveyance of liquids to create.
Jetzt kann man zur Erzeugung einer mechanischen Verbindung zwischen hintereinandergeschalteten Endabschnitt von zwei Rohren Verbindungselemente verwenden, die an den entgegengesetzten Enden von den beiden zu verbindenden Rohren angeschlossen werden können. Jedes Verbindungselement umfasst einen ersten Abschnitt, der am Endabschnitt des jeweiligen Rohres angeschlossen wird, und einen zweiten Abschnitt zum lösbaren Eingriff am anderen Verbindungselement. Die mechanische Verbindung zwischen den beiden Verbindern wird typischerweise durch Gewinde- oder Bajonettkopplungen, Luer-Anschlüssen und ähnlichen erhalten.Now can be used to create a mechanical connection between successive End section of two pipes using fasteners that at the opposite ends of the two pipes to be connected can be connected. Each connecting element comprises a first section, which on the End portion of the respective pipe is connected, and a second section for releasable engagement at the other connection element. The mechanical connection between the two connectors are typically threaded or bayonet couplings, Luer connectors and similar receive.
Es ist aber klar, daß die oben beschriebenen Verbindungsvorrichtungen nur eine mechanische Verbindung zwischen den beiden Endabschnitten des Rohres erzeugen und, wenn erforderlich, die erforderliche Fluid-Dichtheit gewährleisten können.It But it is clear that the above-described connecting devices only a mechanical connection create between the two end portions of the tube and, if required to ensure the required fluid tightness can.
Es gibt aber medizinische Anwendungen, bei den es erforderlich ist, die mechanische Verbindung zwischen den beiden zu verbindenden Rohren erzeugen zu können, aber auch den Fluss durch die verbundenen Rohren überwachen zu können. Insbesondere, wenn zwei Fluid-Förderleitungen miteinander verbunden werden sollen, ist es oftmals erforderlich, den Fluss anzuhalten, wenn die beiden Leitungen ausgeschaltet sind, und den Fluid-Fluss sofort wieder einzuschalten, wenn die beiden Leitungen korrekt verbunden sind.It but there are medical applications that require it the mechanical connection between the two pipes to be connected to be able to produce but also monitor the flow through the connected pipes to be able to. In particular, if two fluid delivery lines It is often necessary to connect to stop the flow when the two lines are off, and turn the fluid flow back on immediately if the two Lines are connected correctly.
Mit Bezug z.B. auf peritonealer Dialyse, ist es typischerweise erforderlich, eine Verbindung zwischen eine am Patient angeschlossenen Leitung, die in Fluid-Verbindung mit dem Inneren des Peritoneums steht, und mindestens einer Infusions-/Ablaufleitung zur Förderung von Flüssigkeiten ins oder vom Peritoneum des Patienten zu erzeugen.With Reference e.g. on peritoneal dialysis, it is typically required a connection between a line connected to the patient, which is in fluid communication with the interior of the peritoneum, and at least one infusion / drain line for the delivery of liquids into or out of the patient's peritoneum.
Zu diesem Zweck, wenn die oben beschriebenen Verbinder verwendet werden sollen, kann der Patient oder ein Techniker die physische Verbindung zwischen der am Patient angeschlossenen Leitung und einem Endabschnitt der Infusions-/Ablaufleitung durchführen.To this purpose, when the connectors described above are used should, the patient or a technician can make the physical connection between the line connected to the patient and an end section of the Perform infusion / drain line.
Damit das System korrekt funktioniert, sollten die Infusions-/Ablaufleitungen und das mit dem Patient verbundene Rohr jeweils Klemmen oder Flussverhinderungselemente aufweisen, die typischerweise in der Nahe von dem Endabschnitt des jeweiligen Rohres liegen und zwischen einer offenen Lage, bei der sie auf dem jeweiligen Rohr nicht wirken, und einer geschlossenen Lage, bei der sie das Rohr drücken, so daß der Flüssigkeitsfluss durch das Rohr angehalten wird, umgeschaltet werden können. Um es anders zu sagen, sollten die mit dem Peritoneum des Patienten verbundene feste Leitung und die Infusions-/Ablaufleitung mit geeigneten Mitteln ausgestattet sein, die den Austritt von Flüssigkeit verhindern, bis der Techniker die beiden Leitungen zusammen verbunden hat.In order to The system should work properly, should the infusion / drain lines and the tube connected to the patient respectively has clamps or flow prevention elements typically close to the end portion of the respective one Pipe lying and between an open position, where they are on the respective pipe does not act, and a closed position, at they push the pipe, so that the liquid flow through the tube is stopped, can be switched. Around To put it another way, those with the patient's peritoneum should connected fixed line and the infusion / drain line with appropriate Be equipped with means that allow the escape of liquid prevent the technician connecting the two wires together Has.
Aus einem Betriebsstandpunkt sollte eine spezifische Prozedur bei der Durchführung irgendeiner Verbindungsoperation zwischen der Infusions-/Ablaufleitung und dem mit dem Patienten verbundenen Rohrabschnitt ausgeführt werden: Zuerst sollten eventuelle Schließelemente, die am Ende jedes Verbinders liegen, entfernt werden, dann sollte die mechanische Verbindung zwischen der mit dem Patienten verbundenen Leitung und der Infusions-/Ablaufleitung erzeugt werden, sowie endlich sollten die Klemmen geöffnet werden.Out An operating point should have a specific procedure during the execution any connection operation between the infusion / drain line and the tube section connected to the patient: First, any closing elements should be at the end of each Connectors lie, be removed, then the mechanical Connection between the line connected to the patient and the infusion / drain line are generated, as well as finally should the terminals open become.
Die obige Beschreibung zeigt deutlich, daß viele manuelle Operationen zur Erzeugung und Entfernung der Verbindung erforderlich sind. Der Grund daraus besteht in dem Aufbau der Verbinder und darin, daß die verwendeten Verbinder und Flussverhinderungselemente (Klemmen) voneinander funktional unabhängig sind.The above description clearly shows that many manual operations necessary to generate and remove the connection. Of the The reason for this is the structure of the connectors and that the used Connector and flow prevention elements (terminals) are functionally independent of each other.
Weiter kann die beschriebene Lösung in einigen Situationen als vorteilhaft zum Bakterienwachstum angesehen werden.Further can the described solution considered beneficial for bacterial growth in some situations become.
Insbesondere wird der sich zwischen jeder Flussverhinderungsklemme und dem Ende des Rohres erstreckende Leitungsabschnitt bei der Verwendung nur durch den Fluss befeuchtet. Obwohl theoretisch am Anfang und am Ende jeder Behandlung dieser Abschnitt einer Wasch- und Desinfektionsprozedur unterworfen ist, sollte der Anwender natürlich darauf beachten, die Möglichkeit vom Bakterienwachstum abzunehmen.Especially will be between each flow prevention clamp and the end the tube extending line section in use only moistened by the river. Although theoretically at the beginning and at the End of each treatment this section of a washing and disinfecting procedure subject, of course, the user should pay attention to the possibility to decrease from bacterial growth.
Aufgrund der Begrenzungen der oben beschriebenen Verbinder wurden andere technischen Lösungen in der Vergangenheit versucht, die nun kurz erläutert werden.by virtue of the boundaries of the connectors described above have changed technical solutions tried in the past, which will now be explained briefly.
US Patent Nr. 5 743 892 erläutert ein Verbindungssystem zur peritonealen Dialyse umfassend einen ersten Verbinder an einem Patienten anschließbaren Rohr, und einen zweiten Verbinder, der an einem Infusions-/Ablaufrohr angeschlossen ist. Bei der Kopplung der beiden Verbinder desinfiziert ein am zweiten Verbinder liegendes ringförmiges Element den Kopplungsabschnitt des ersten Verbinders. Die Verbinder umfassen auch eine Klemme, die zur Verhinderung oder Einstellung des Flusses durch die Verbinder manuell zu betätigen ist.US Pat. No. 5,743,892 discloses a peritoneal dialysis connection system comprising a first connector on a patient-connectable tube, and a second connector attached to a patient nem infusion / drain pipe is connected. When coupling the two connectors, an annular member located on the second connector disinfects the coupling portion of the first connector. The connectors also include a clamp which is manually operable to prevent or adjust the flow through the connectors.
Diese Lösung löst nicht das Problem der erforderlichen komplexen Handbewegungen, da die Funktionen von mechanischer Verbindung und Flussverhinderung getrennt sind. Auch wirken die Klemmen von jedem Verbinder bei einem Abstand von dem freien Ende des jeweiligen Verbinders, was die oben benannten Probleme von Bakterienwachstum nur teilweise löst.These solution does not solve the problem of the necessary complex hand movements, as the functions are separated from mechanical connection and flow prevention. Also, the clamps of each connector act at a distance of the free end of each connector, what the above named Solves problems of bacterial growth only partially.
